Abstract

Critical boundaries in the early Drosophila embryo are set by morphogenetic gradients. A new quantitative study shows that the placement of one such boundary is more accurate than the gradient thought to set it. Genetic analysis of the accuracy of the process implicates a gene not previously thought to be involved.

摘要

果蝇早期胚胎中的关键边界是由形态发生梯度设定的。一项新的定量研究表明，其中一个这样的边界的位置比人们认为设定它的梯度更精确。对这一过程准确性的遗传分析表明，一个以前认为与之无关的基因也与之有关。
